Refrigerator and water drainage device thereof

Abstract

The invention discloses a refrigerator and a water drainage device thereof. The water drainage device comprises a water drainage pipe, a water drainage outlet cover and an overflowing pipe, wherein the water drainage pipe comprises a water inlet, a water drainage outlet and an overflowing port which is positioned between the water inlet and the water drainage outlet; the water drainage outlet cover is used for covering the water drainage outlet; the water drainage outlet cover allows water to be drained from the water drainage outlet and prevents gas from entering the water drainage pipe fromthe water drainage outlet; one end of the overflowing pipe is connected with the overflowing port, and the other end of the overflowing pipe is provided with an overflowing valve; and the overflowingvalve allows the water to be drained from the overflowing pipe and prevents the gas from entering the water drainage pipe from the overflowing pipe. According to the water drainage device for the refrigerator provided by the embodiment of the invention, the back-suction of external heat humidity gas into a refrigerator body due to a difference between an interior pressure of the refrigerator and an atmospheric pressure can be prevented, so refrigerating efficiency cannot be influenced. An auxiliary water drainage function is realized, so the water drainage of the refrigerator is smoother.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a drainage device and a refrigerator with the drainage device. Background technique [0002] The current drainage system of the refrigerator simply discharges the defrosted water and waste water in the refrigerator out of the box, without considering the pressure difference between the pressure inside the box and the atmospheric pressure, which causes the backflow of hot and humid air in the drain pipe outside the box. The cooling efficiency of the refrigerator system is affected, and the hot and humid air backflows and freezes, resulting in incomplete defrosting, resulting in low cooling efficiency and incomplete cooling of the refrigerator. On the other hand, the current refrigerators do not discharge a large amount of defrosting water at the same time under harsh conditions, resulting in untimely drainage or even blocked drainage pipes, or excessive pressure at the drain...

[0002] The current drainage system of the refrigerator simply discharges the defrosted water and waste water in the refrigerator out of the box, without considering the pressure difference between the pressure inside the box and the atmospheric pressure, which causes the backflow of hot and humid air in the drain pipe outside the box. The cooling efficiency of the refrigerator system is affected, and the hot and humid air backflows and freezes, resulting in incomplete defrosting, resulting in low cooling efficiency and incomplete cooling of the refrigerator

On the other hand, the current refrigerators do not discharge a large amount of defrosting water at the same time under harsh conditions, resulting in untimely drainage or even blocked drainage pipes, or excessive pressure at the drain outlet, resulting in poor drainage of the refrigerator, etc. proposed improvements
